摘要：

Dispersed nanoparticles are introduced from stabilized suspensions during the 1 accumulative roll bonding process in aluminium AA1050A by air gun spraying up to a final volume I fraction of 0.1 % after eight cycles. Additional strengthening caused by particle insertion is observed and strongly depends on the suspension medium and stabilizing agent as both influence interfacial I bonding of the particles to the matrix. The particle insertion furthermore results in reduced peel 1 strength of the sheets irrespective of particle material and size caused by a reduction of effective metal : to metal bonding area during rolling through the presence of the particles.
